Problems solved by technology

[0005] However, in the above-mentioned switch, since the contact parts are connected to each other through the arm extending along the sliding direction of the movable contact, when the switch is increased in capacity, the generated arc spreads over the extending direction of the arm. The wrist part is deteriorated in a wide range, and each contact part may not function as a contact point

Abstract

The present invention provides a switch capable of reducing deterioration of a movable contact piece due to generated arcs and achieving high capacity. The switch of the present invention includes a case (10), a general fixed contact side terminal (20), an individual fixed contact side terminal (30), and a plunger (40) having a movable contact piece (50). The movable contact piece (50) has: a main body portion (51), extending from the main body portion (51) in a direction intersecting with the parallel direction of the general fixed contact side terminal (20) and the individual fixed contact side terminal (30). The first wrist part (52), the second wrist part (53), the third wrist part (54), which are electrically connected to each other and are spaced apart from each other in the parallel direction, are arranged on the first wrist part (52) The first movable contact (521), the second movable contact (531) on the second wrist (53), the third movable contact (541) on the third wrist (54) .

Description

technical field [0001] The present invention relates to switches. Background technique [0002] A switch is disclosed in Patent Document 1, which includes: a housing having a storage portion, a universal fixed contact and an individual fixed contact electrically independently provided on the inner bottom surface of the storage portion, and a drive unit detachably provided in the storage portion. The component, the movable contact that slides with the general fixed contact and the individual fixed contact as the driving component is inserted into the storage portion. [0003] In the above switch, the movable contacts are provided with independent second and third contact portions which hold individual fixed contacts and slide individually, and the individual fixed contacts are provided with movable contacts. The first contact portion for arc consumption that contacts the second contact portion of the point, and the second contact portion that contacts the third contact porti...
